These shirts are great. However, the sleeves on the Large size are probably 33 inches, a little too short for me, but no big deal, as I typically roll my sleeves up. When I don't, the sleeve length doesn't really bother me.
Let me start off by saying I'm a redhead, so I burn EASY. This is why I purchased this shirt. With the sleeves down I do not burn while working in full sun. This shirt has good sun protection. This shirt has decent venting. You will be warm while wearing this shirt with the sleeves down. The problem I have is the shoulder width and under arm constraints. While wearing this shirt while working I feel constrained with my arms out. A longer shirt as in a Tall will not fix this issue. There needs to be a fix for the shoulder and under arms. I would improve this shirt by adding a gusset under the arms and widening the shoulder by 1/2 inch min. This would make this shirt more comfortable to wear.
Gave this to my husband for a gift. He pointed it out to mr. He has other colors from previous years. He wears this shirt so much that it is hard for me to get into the washer!
